British Birds in their Haunts Part 22

THE GREEN WOODp.e.c.k.e.r GeCINUS VIRIDIS

Upper plumage green; under, greenish ash; crown, back of the head, and moustaches crimson; face black. _Female_--less crimson on the head; moustaches black. Length thirteen inches; breadth twenty-one inches. Eggs glossy white.

One of the most interesting among the natural sounds of the country, is that of the

Woodp.e.c.k.e.r tapping the hollow beech tree:

yet one may walk through the woods many times and hear no tapping at all, and even if such a sound be detected and traced to its origin, it will often be found to proceed from the Nuthatch, who has wedged a hazel-nut into the bark of an oak, than from the hammering of a Woodp.e.c.k.e.r. Yet often indeed it may be observed ascending, by a series of starts, the trunk of a tree, inclining now a little to the right, and now to the left, disappearing now and then on the side farthest from the spectator, and again coming into view somewhat higher up. Nor is its beak idle; this is employed sometimes in dislodging the insects which lurk in the rugged bark, and sometimes in tapping the trunk in order to find out whether the wood beneath is sound or otherwise. Just as a carpenter sounds a wall with his hammer in order to discover where the brickwork ends and where lath and plaster begin, so the Woodp.e.c.k.e.r sounds the wooden pillar to which it is clinging, in order to discover where the wood is impenetrable alike by insects and itself, and where the former have been beforehand with it in seeking food or shelter. Such a canker-spot found, it halts in its course, tears off piece-meal a portion of bark and excavates the rotten wood beneath, either as far as the fault extends or as long as it can find food. It is, then, by no means a mischievous bird, but the reverse; as it not only destroys a number of noxious insects, but points out to the woodman, if he would only observe aright, which trees are beginning to decay and consequently require his immediate attention.

This aspect of the Woodp.e.c.k.e.r's operations is the right one and not the old idea that 'it is a great enemy of old trees in consequence of the holes which it digs in their trunks', as some old writer states.

But with all his digging and tapping, the sound by which the vicinity of a Woodp.e.c.k.e.r is most frequently detected, especially in spring and summer, is the unmistakable laughing note which has gained for him the name of 'Yaffle.' No more perhaps than the mournful cooing of the dove does this indicate merriment; it is harsh, too, in tone; yet it rings through the woods with such jovial earnestness that it is always welcome. On such occasions the bird is not generally, I think, feeding, for if the neighbourhood from which the sound proceeded be closely watched, the Yaffle may frequently be observed to fly away, with a somewhat heavy dipping flight, to another tree or grove, and thence, after another laugh, to proceed to a second. It is indeed oftener to be seen on the wing than hunting for food on the trunks of trees. Very frequently too it may be observed on the ground, especially in a meadow or common in which ants abound.

The admirable adaptation of the structure of the Woodp.e.c.k.e.r to its mode of life is well pointed out by Yarrell. Its sharp, hooked toes, pointing two each way, are eminently fitted for climbing and clinging.

The keel of the breast-bone is remarkably shallow; hence, when ascending (its invariable mode of progress) a tree, it is enabled to bring its body close to the trunk without straining the muscles of the legs. Its tail is short, and composed of unusually stiff feathers, which in the process of climbing are pressed inwards against the tree, and contribute greatly to its support. The beak is strong and of considerable length, and thus fitted either for digging into an ant-hill or sounding the cavities of a tree; and the tongue, which is unusually long, is furnished with a curious but simple apparatus, by which it is extended so that it can be thrust into a hole far beyond the point of the bill, while its tip is barbed with small filaments, which, like the teeth of a rake, serve to pull up the larva or insect into its mouth. The Woodp.e.c.k.e.r builds no nest, but lays five or six glossy white eggs on the fragments of the decayed wood in which it has excavated its nest.

Other names by which this bird is known are Popinjay, Wood-sprite, Rain-bird, Hew-hole and Woodweele.

SUB-FAMILY IYNGINae

THE WRYNECK IYNX TORQUILLA

Upper plumage reddish grey, irregularly spotted and lined with brown and black; a broad black and brown band from the back of the head to the back; throat and breast yellowish red, with dusky transverse rays; rest of the under plumage whitish, with arrow shaped black spots; outer web of the quills marked with rectangular alternate black and yellowish red spots; tail-feathers barred with black zigzag bands; beak and feet olive brown. Length six inches and a half; breadth eleven inches. Eggs glossy white.

The note of the Wryneck is so peculiar that it can be confounded with none of the natural sounds of the country; a loud, rapid, harsh cry of _pay-pay-pay_ from a bird about the size of a lark may be referred without hesitation to the Wryneck. Yet it is a pleasant sound after all--'the merry pee-bird' a poet calls it--and the untuneful minstrel is the same bird which is known by the name of 'Cuckoo's Mate', and so is a.s.sociated with May-days, pleasant jaunts into the country, hayfields, the memory of past happy days and the hope of others to come. This name it derives not from any fondness it exhibits for the society of the cuckoo, as it is a bird of remarkably solitary habits, but because it arrives generally a few days before the cuckoo. Not less singular than its note is its plumage, which, though unmarked by gaudiness of colouring, is very beautiful, being richly embroidered as it were with brown and black on a reddish grey ground. In habits, it bears no marked resemblance to the Woodp.e.c.k.e.rs; it is not much given to climbing and never taps the trunks of trees; yet it does seek its food on decayed trees, and employs its long h.o.r.n.y tongue in securing insects. It darts its tongue with inconceivable rapidity into an ant-hill and brings it out as rapidly, with the insects and their eggs adhering to its viscid point. These const.i.tute its princ.i.p.al food, so that it is seen more frequently feeding on the ground than hunting on trees. But by far the strangest peculiarity of the Wryneck, stranger than its note and even than its worm-like tongue, is the wondrous pliancy of its neck, which one might almost imagine to be furnished with a ball and socket joint. A country boy who had caught one of these birds on its nest brought it to me on a speculation. As he held it in his hand, I raised my finger towards it as if about to touch its beak. The bird watched most eagerly the movement of my finger, with no semblance of fear, but rather with an apparent intention of resenting the offer of any injury. I moved my finger to the left; its beak followed the direction--the finger was now over its back, still the beak pointed to it. In short, as a magnetic needle follows a piece of steel, so the bird's beak followed my finger until it was again in front, the structure of the neck being such as to allow the head to make a complete revolution on its axis, and this without any painful effort. I purchased the bird and gave it its liberty, satisfied to have discovered the propriety of the name Torquilla.[20] I may here remark that the name Iynx,[21] is derived from its harsh cry. Besides this, the proper call-note of the bird, it utters, when disturbed in its nest, another which resembles a hiss; whence and partly, perhaps, on account of the peculiar structure of its neck, it is sometimes called the Snake-bird. Nest, properly speaking, it has none; it selects a hole in a decaying tree and lays its eggs on the rotten wood. Its powers of calculating seem to be of a very low order.

Yarrell records an instance in which four sets of eggs, amounting to twenty-two, were successively taken before the nest was deserted; a harsh experiment, and scarcely to be justified except on the plea that they were taken by some one who gained his livelihood by selling eggs, or was reduced to a strait from want of food. A similar instance is recorded in the _Zoologist_, when the number of eggs taken was also twenty-two. The Wryneck is a common bird in the south-eastern counties of England and to the west as far as Somersets.h.i.+re; but I have never heard its note in Devon or Cornwall; it is rare also in the northern counties.

FAMILY ALCEDINIDae

THE KINGFISHER ALCeDO iSPIDA

Back azure-blue; head and wing-coverts bluish green, spotted with azure-blue; under and behind the eye a reddish band pa.s.sing into white, and beneath this a band of azure-green; wings and tail greenish blue; throat white; under plumage rusty orange-red. Length seven inches and a quarter; width ten inches. Eggs glossy white, nearly round.

Halcyon days, every one knows, are days of peace and tranquillity, when all goes smoothly, and nothing occurs to ruffle the equanimity of the most irascible member of a household; but it may not be known to all my younger readers that a bird is said to be in any way concerned in bringing about this happy state of things. According to the ancient naturalists the Halcyon, our Kingfisher, being especially fond of the water and its products, chooses to have even a floating nest. Now the surface of the sea is an unfit place whereon to construct a vessel of any kind, so the Halcyon, as any other skilful artisan would, puts together on land first the framework, and then the supplementary portion of its nest, the materials being sh.e.l.ly matter and spines, whence derived is unknown; but the princ.i.p.al substance employed is fish-bones. During the progress of the work the careful bird several times tests its buoyancy by actual experiment, and when satisfied that all is safe, launches its future nursery on the ocean. However turbulent might have been the condition of the water previously to this event, thenceforth a calm ensued, which lasted during the period of incubation; and these were 'Halcyon days' (_Halcyonides dies_), which set in seven days before the winter solstice, and lasted as many days after. What became of the young after the lapse of this period is not stated, but the deserted nest itself, called halcyoneum, identical, perhaps, with what we consider the sh.e.l.l of the echinus, or sea-urchin, was deemed a valuable medicine.[22]

The real nest of the Kingfisher is a collection of small fish-bones, which have evidently been disgorged by the old birds. A portion of one which I have in my possession, and which was taken about twenty years since from a deep hole in an embankment at Deepdale, Norfolk, consists exclusively of small fish-bones and sc.r.a.ps of the sh.e.l.ls of shrimps. A precisely similar one is preserved in the British Museum, which is well worthy the inspection of the curious. It was found by Mr. Gould in a hole three feet deep on the banks of the Thames; it was half an inch thick and about the size of a tea saucer, and weighed 700 grains.

Mr. Gould was enabled to prove that this ma.s.s was deposited, as well as eight eggs laid, in the short s.p.a.ce of twenty-one days. In neither case was there any attempt made by the bird to employ the bones as materials for a structure; they were simply spread on the soil in such a way as to protect the eggs from damp, possessing probably no properties which made them superior to bents or dry leaves, but serving the purpose as well as anything else, and being more readily available, by a bird that does not peck on the ground, than materials of any other kind.

The wanderer by the river's side on a bright sunny day, at any season, may have his attention suddenly arrested by the sight of a bird shooting past him, either up or down the stream, at so slight an elevation above the water, that he can look down on its back. Its flight is rapid, and the colour of the plumage so brilliant, that he can compare it to nothing less dazzlingly bright than the richest feathers of the peac.o.c.k, or a newly dug specimen of copper ore. After an interval of a few seconds it will perhaps be followed by a second, its mate, arrayed in attire equally gorgeous with emerald, azure, and gold. Following the course of the bird, let him approach cautiously any pools where small fish are likely to abound, and he may chance to descry, perched motionless on the lower branch of an alder overhanging the stream, on some bending willow, or lichen-covered rail, the bird which but now glanced by him like a meteor. If exposed to the rays of the sun, the metallic green of its upper plumage is still most conspicuous; if in the shade, or surrounded by leaves, its chestnut red breast betrays its position. Not a step further in advance, or the fisherman, intent as he is on his sport, will take alarm and be off to another station. With beak pointed downwards it is watching until one among a shoal of minnows or bleaks comes within a fair aim; then with a twinkle of the wing it dashes head foremost from its post, plunges into the stream, disappears for a second, and emerges still head foremost with its struggling booty. A few pinches with its powerful beak, or a blow against its perch, deprives its prey of life, and the morsel is swallowed entire, head foremost. Occasionally, where convenient perches are rare, as is the case with the little pools left by the tide on the sea-sh.o.r.e (for the Kingfisher is common on the banks of tidal rivers as well as on inland streams and lakes), it hovers like a Kestrel, and plunges after small fish, shrimps, and marine insects. It once happened to me that I was angling by a river's side, quite concealed from view by a willow on either side of me, when a Kingfisher flew down the stream, and perched on my rod. I remained perfectly still, but was detected before an opportunity had been afforded me of taking a lesson from my brother sportsman.

The Kingfisher is a permanent resident in this country, and may be observed, at any season, wherever there is a river, ca.n.a.l, or lake, those streams being preferred the banks of which are lined with trees or bushes. Like most other birds of brilliant plumage, it is no vocalist; its only note being a wild piping cry, which it utters while on the wing. Happily the Kingfishers are again on the increase in our country.

FAMILY CORACIIDae

THE ROLLER CORaCIAS GaRRULUS

Head, neck, and under parts tinged with various shades of light blue, varied with green; back and scapulars reddish brown; tail blue, green, and black. Length twelve inches and a half. Eggs smooth s.h.i.+ning white.

About twenty specimens in all of this bird have been observed in England, the one of most recent occurrence being, I believe, one which was shot close to my garden, on the twentieth of September, 1852. The winter home of the Roller is Africa, and it is said to be particularly abundant in Algeria. About the middle of April it crosses the Mediterranean, and seems to prefer the north of Europe to the south as a summer residence, being more abundant in Germany and the south of Russia than in France, though many proceed no further than Sicily and Greece. Its food consists mainly of caterpillars and other insects.

The name Roller, being derived directly from the French _Rollier_, should be p.r.o.nounced so as to rhyme with 'dollar'.

FAMILY MEROPIDae

THE BEE-EATER MeROPS APIaSTER

Forehead white, pa.s.sing into bluish green; upper plumage chestnut; throat golden yellow, bounded by a black line; wings variegated with blue, brown, and green; tail greenish blue.

Length eleven inches. Eggs glossy white.

This bird, which in brilliancy of plumage vies with the Hummingbirds, possesses little claim to be ranked among soberly clad British birds.

Stray instances are indeed met with from time to time, but at distant intervals. In the islands of the Mediterranean, and in the southern countries of Europe, they are common summer visitors, and in Asia Minor and the south of Russia they are yet more frequent. They are gregarious in habits, having been observed, both in Europe, their summer, and in Africa, their winter residence, to perch together on the branches of trees in small flocks. They also build their nests near each other. These are excavations in the banks of rivers, variously stated to be extended to the depth of from six inches to as many feet. Their flight is graceful and light, resembling that of the Swallows. Their food consists of winged insects, especially bees and wasps, which they not only catch when they are wandering at large through the air, but watch for near their nests. The inhabitants of Candia and Cyprus are said to catch them by the help of a light silk line, to which is attached by a fish-hook a wild bee. The latter in its endeavour to escape soars into the air, and the Bee-eater seizing it becomes the prey of the aerial fisherman.

FAMILY UPUPIDae

THE HOOPOE UPUPA EPOPS

Crest orange-red tipped with black; head, neck, and breast pale cinnamon; back, wings, and tail barred with black and white; under parts white. Length twelve inches; width nineteen inches.

Eggs lavender grey, changing to greenish olive.

Little appears to be known of the habits of this very foreign-looking bird from observation in Great Britain. The season at which it is seen in this country is usually autumn, though a few instances have occurred of its having bred with us. In the south of Europe and north of Africa it is of common occurrence as a summer visitor, but migrates southwards in autumn. Its English name is evidently derived from the French _Huppe_, a word which also denotes 'a crest', the most striking characteristic of the bird. It is called also in France _Puput_, a word coined, perhaps, to denote the noise of disgust which one naturally makes at encountering an unpleasant odour, this, it is said, being the constant accompaniment of its nest, which is always found in a filthy condition, owing to the neglect of the parent birds in failing to remove offensive matter, in conformity with the laudable practise of most other birds. In spite of the martial appearance of its crest, it is said to be excessively timid, and to fly from an encounter with the smallest bird that opposes it. It lives princ.i.p.ally on the ground, feeding on beetles and ants. On trees it sometimes perches but does not climb, and builds its nest in holes in trees and walls, rarely in clefts of rocks. It walks with a show of dignity when on the ground, erecting its crest from time to time. In spring the male utters a note not unlike the coo of a Wood-pigeon, which it repeats several times, and at other seasons it occasionally emits a sound something like the shrill note of the Greenfinch. But it is no musician and is as little anxious to be heard as seen. The nest is a simple structure composed of a few sc.r.a.ps of dried gra.s.s and feathers, and contains from four to six eggs. It would breed here annually if not always shot on arrival.

FAMILY CUCULIDae

THE CUCKOO CuCULUS CANoRUS

Upper plumage bluish ash colour, darker on the wings, lighter on the neck and chest; under parts whitish with transverse dusky streaks; quills barred on the inner webs with oval white spots; tail-feathers blackish, tipped and spotted with white; bill dusky, edged with yellow; orbits and inside of the mouth orange-yellow; iris and feet yellow. _Young_--ash-brown, barred with reddish brown; tips of the feathers white; a white spot on the back of the head. Length thirteen inches and a half, breadth twenty-three inches. Eggs varying in colour and markings.

No bird in a state of nature utters a note approaching so closely the sound of the human voice as the Cuckoo; on this account, perhaps, partially at least, it has at all times been regarded with especial interest. Its habits have been much investigated, and they are found to be unlike those of any other bird. The Cuckoo was a puzzle to the earlier naturalists, and there are points in its biography which are controverted still. From the days of Aristotle to those of Pliny, it was supposed to undergo a metamorphosis twice a year, appearing during the summer months as a Cuckoo, "a bird of the hawk kind, though dest.i.tute of curved talons and hooked beak, and having the bill of a Pigeon; should it chance to appear simultaneously with a Hawk it was devoured, being the sole example of a bird being killed by one of its own kind. In winter it actually changed into a Merlin, but reappeared in spring in its own form, but with an altered voice, laid a single egg, or rarely two, in the nest of some other bird, generally a Pigeon, declining to rear its own young, because it knew itself to be a common object of hostility among all birds, and that its brood would be in consequence unsafe, unless it practised a deception. The young Cuckoo being naturally greedy, monopolized the food brought to the nest by its foster parents; it thus grew fat and sleek, and so excited its dam with admiration of her lovely offspring, that she first neglected her own chicks, then suffered them to be devoured before her eyes, and finally fell a victim herself to his voracious appet.i.te."[23]--A strange fiction, yet not more strange than the truth, a glimmering of which appears throughout. We know well enough now that the Cuckoo does not change into a Merlin, but migrates in autumn to the southern regions of Africa; but this neither Aristotle nor Pliny could have known, for the common belief in their days was, that a continued progress southwards would bring the traveller to a climate too fierce for the maintenance of animal life. Now the Merlin visits the south of Europe, just at the season when the Cuckoo disappears, and returns northwards to breed in spring, a fact in its history as little known as the migration of the Cuckoo. It bears a certain resemblance to the Cuckoo, particularly in its barred plumage, certainly a greater one than exists between a caterpillar and a b.u.t.terfly, so that there were some grounds for the belief in a metamorphosis, strengthened not a little by the fact that the habits of the bird were peculiar in other respects. Even so late as the time of our own countrymen, Willughby and Ray (1676), it was a matter of doubt whether the Cuckoo lay torpid in a hollow tree, or migrated during winter. These authors, though they do not admit their belief of a story told by Aldrovandus of a certain Swiss peasant having heard the note of a Cuckoo proceed from a log of wood which he had thrown into a furnace, thought it highly probable that the Cuckoo did become torpid during winter, and were acquainted with instances of persons who had heard its note during unusually mild winter weather. A Cuckoo which had probably been hatched off too late to go away with the rest remained about the tennis ground of a relative of the present editor until the middle of November, getting very tame. Then, unfortunately, a cat got it. The a.s.sertion again of the older naturalists, that the Cuckoo is the object of hatred among birds generally, seems credible, though I should be inclined to consider its habit of laying its eggs in the nests of other birds as the cause rather than the consequence of its unpopularity. The contrary, however, is the fact, numerous anecdotes of the Cuckoo showing that it is regarded by many other birds with a respect which amounts to infatuation, rather than with apprehension. The statement that it lays but one egg is erroneous, so also is the a.s.sertion of Willughby that it invariably destroys the eggs found in a nest previously to depositing its own. Pliny's a.s.sertion that the young bird devours its foster brothers and sisters is nearer the truth, but his account of its crowning act of impiety in swallowing its nurse, is, I need not say, altogether unfounded in fact. Having disposed of these errors, some of which are entertained by the credulous or ill-informed at the present day, I will proceed to sketch in outline the biography of this singular bird, as the facts are now pretty generally admitted.

The Cuckoo arrives in this country about the middle of April; the time of its coming to different countries is adapted to the time of the foster-parents' breeding. During the whole of its stay it leads a wandering life, building no nest, and attaching itself to no particular locality. It shows no hostility towards birds of another kind, and little affection for those of its own. If two males meet in the course of their wandering they frequently fight with intense animosity. I was once witness of an encounter between two birds who chanced to meet in mid-air. Without alighting they attacked each other with fury, pecking at each other and changing places just as one sees two barn-door c.o.c.ks fight for the supremacy of the dunghill. Feathers flew in profusion, and in their pa.s.sion the angry birds heeded my presence so little that they came almost within arm's length of me.

These single combats account for the belief formerly entertained that the Cuckoo was the only sort of Hawk that preyed on its own kind. The female does not pair or keep to one mate. It is, however, frequently accompanied by a small bird of another kind, said to be a Meadow Pipit.

The Cuckoo hunts for its food both in trees and on the ground. On its first arrival it lives princ.i.p.ally on beetles, but when caterpillars become abundant it prefers them, especially the hairy sorts. In the months of May and June, the female Cuckoo lays her eggs (the number of which is variously estimated from five to twelve), choosing a separate locality for each, and that invariably the nest of some other bird.

The nests in which the egg of a Cuckoo has been found in this country are those of the Hedge Sparrow, Robin, Redstart, Whitethroat, Willow Warbler, Sedge Warbler, Wagtail, Pipit, Skylark, Yellow Bunting, Chaffinch, Greenfinch, Linnet, Blackbird and Wren; the Pipit being the most frequent. It has now been ascertained that the nests of birds in which the Cuckoo lays its eggs in different countries number 145 species.[24] In some of these instances, the position and structure of the nests were such that a bird of so large a size could not possibly have laid an egg in the usual way. Hence, and from other evidence, it is pretty clear that the egg is in all cases laid at a distance from the nest and carried by the bird in her bill to its destination. The bird can have no difficulty in accomplis.h.i.+ng this seemingly hard task; for the gape of the Cuckoo is wide, and the egg disproportionately small, no larger in fact than the egg of the Skylark, a bird only a fourth of its size. The period during which a nest is fit for the reception of a Cuckoo's egg is short; if a time were chosen between the completion of the nest and the laying of the first egg by the rightful owner, the Cuckoo could have no security that her egg would receive incubation in good time, and again if the hen were sitting there would be no possibility of introducing her egg surrept.i.tiously.

She accordingly searches for a nest in which one egg or more is laid, and in the absence of the owner lays down her burden and departs.

There are certain grave suspicions that the intruder sometimes makes room for her own egg by destroying those already laid; but this, if it be true, is exceptional. If it were very much larger than the rest, it might excite suspicion, and be either turned out, or be the cause of the nest being deserted; it would require, moreover, a longer incubation than the rest, and would either fail to be hatched, or produce a young Cuckoo at a time when his foster-brothers had grown strong enough to thwart his evil designs. As it is, after fourteen days' incubation, the eggs are hatched simultaneously, or nearly so, the Cuckoo being generally the first. No sooner does the young bird see the day, than he proceeds to secure for himself the whole s.p.a.ce of the nest and the sole attention of his foster-parents, by insinuating himself under the other young birds and any eggs which may remain unhatched, and hurling them over the edge of the nest, where they are left to perish. 'The singularity of its shape', says Dr. Jenner, 'is well adapted for these purposes; for, different from other newly-hatched birds, its back from the shoulders downwards is very broad, with a considerable depression in the middle. To the question which naturally suggests itself, 'Why does the young Cuckoo thus monopolize the nest and the attentions of its foster parents?' the solution is plain. The newly-hatched bird must of necessity be less in size than the egg from which it proceeded, but a full-grown Cuckoo exceeds the dimensions of a whole brood of Pipits; its growth therefore must be rapid and cannot be maintained without a large supply of food. But the old birds could not possibly with their utmost exertions feed a brood of their own kind and satisfy the demands made by the appet.i.te of the voracious stranger as well. The latter consequently saves them from this impossible task, and, by appropriating to his single use the nourishment intended for a brood of four or five, not only makes provision for his own well-being, but helps them out of a difficulty. So a.s.siduously is he taken care of that he soon becomes a portly bird and fills his nest; in about three weeks he is able to fly, but for a period of four or five weeks more his foster-parents continue to feed him. It is probable that the young Cuckoo actually exercises some fascination over other birds. There is a case on record in which a pair of Meadow Pipits were seen to throw out their own young ones to make room for the intruder. In another instance, a young Cuckoo which had been taken from the nest and was being reared by hand escaped from confinement. Having one of its wings cut, it could not fly, but was found again, at the expiration of a month, within a few fields of the house where it was reared, and several little wild birds were in the act of feeding it. The Bishop of Norwich[25] mentions two instances in which a young Cuckoo in captivity was fed by a young Thrush which had only just learnt to feed itself.

In the days when omens were observed, it was considered a matter of high import to hear the song of the Nightingale before that of the Cuckoo. Thus Chaucer says:
